Each service that you use in your life is business:
1. Drink coffe
2. Eat meal
3. Play Moba games
The difference in your attitude.
From our side, it's reasonable to expand item mall in 3 weeks after server start.
I understood, that you afraid of expand it even more, but we won't.
In other hand, you are adult, and should understood, that if we won't expand it at all, we won't be able to inest money in advertise and support it.
Sooner or later, you will tell us, that we don't watch the server, just look into expirience of official company, they always add new stuff to item mall.
The buttom line is:
We won't add the stuff, which would unbalance game process.
About B-grade, we give you a word to provide the statistics of sell, so you understood, how many players really bought B grade, so far it's 8 users.
About RMT - i don't get your point, because those who provide RMT for server, already provide A/S grade, we know, because hunting for them.
About puting a price for items - i agree with you, but those who became play - will play, those who become for RMT will RMT, you'll never stop it, the only way is fight.
